相反性クリックを有する無歯顎顎関節症患者に対し全部床義歯製作により治療した１症例

Abstract

This case report describes a treatment method for a 68-year-old female with reciprocal clicking on her left temporomandibular joint. Wearing complete dentures for a long time and her unilateral habitual mastication caused this condition. As a countermeasure, an interocclusal record was taken at a position without clicking and a new complete denture set was fabricated. In such a case, we usually expect to adopt a new jaw position by adjusting the old dentures. If the degree of disc displacement or transformation of the disc is severe, mandibular repositioning may be difficult. Furthermore, many aged patients have limitated ability to adapt to a new mandibular position. In this case, the degree of disc displacement was slight, so the patient could accept a new position. After wearing the new dentures, her clicking disappeared and MRI showed reduction of the disc. She was able to accept the new position.
